FAQ:How do I turn off the ActiveRowAppearance so that the active row in the grid does not appear selected.
In that case, I think all you need to do is set the CellClickAction to RowSelect.
Hi,
I'm not sure I understand your question. Are you talking about allowing users to select rows or selecting rows programmatically in code? If it's via user interaction, how do you want the users to select rows? What will they click on without row selectors? Do you just want the rows to be selected when clicked?
